After Congress passed a law allowing women to enlist with children, Margo Parker was the first woman in California to enlist. Years later, both Margo and her husband received orders for Desert Storm while they had six children at home in Tucson, Ariz. Fortunately, Margo was able to serve locally and her husband was deployed to the United Arab Emirates. She raised her children and worked tirelessly for her country while worrying about her husband. This was before the Internet made daily calls and emails possible. Today, Margo and her husband are retired from the Air Force, but she still works full time and helps her children and 14 grandchildren. Many have depended on Margo through the years; she serves a small community in big ways.

Rob Jones is a study in bravery and determination. After losing both legs to an IED in Taliban territory in Afghanistan in 2010, the combat engineer might have given up, but instead he fought back. Rob, who lives in Charlottesville, Va., used his recovery time learning to use his new prosthetic legs and relearning other activities, including rowing. He enjoyed rowing so much he decided to try out for the 2012 Paralympics. After intense training and several qualifying events, Rob and his rowing partner won the bronze in London.

Joe "Kap" Kapacziewski of Upatol, Ga., made history by becoming the first Army Airborne Ranger ever to return to combat after an amputation. Badly wounded in 2005 in Iraq by a grenade explosion, Joe suffered a severed nerve and artery in one arm, deep wounds on his hip and shattered bones in his right leg. He endured more than 42 surgeries on his leg, but it would not heal, and so he allowed doctors to amputate. Returning to Ranger duty on his prosthetic leg, Joe has served five combat deployments as an amputee. In 2010, he dragged a wounded Ranger to safety through relentless enemy gunfire, with the help of another soldier, to save the Ranger's life. The much-decorated Ranger is a mentor with CAF Operation Rebound.

Rich Bennett, of DeKalb, Ill., served in the Army's 101st Airborne Division. During a deployment to Afghanistan, Rich's unit came under fire on a daily basis. While on an air assault mission to the Korengal Valley, Rich, with no thought for his own safety, ran 35 meters through heavy enemy fire and threw himself on the platoon's fallen medic to shield him from further wounds. Heavy fire continued all around as Rich pulled his fellow soldier to cover. That solider is now recovering from his wounds. For his actions, Rich was awarded the Silver Star. He says he only did what any of his fellow infantrymen would have done. Rich is now pursuing a bachelor's degree at Northern Illinois University in DeKalb, and hopes to work with the Wounded Warriors Project after graduation. He is also vice president of the Veterans Club at Northern Illinois University, which works with the local VFW and American Legion to support local veterans.

Israel Del Toro, of Cibolo, Texas, was given a 15 percent chance of survival after an IED explosion left him with third-degree burns over 85 percent of his body.

But Israel did survive, and after 120 surgeries (so far), he is the first 100 percent disabled Airmen to re-enlist in the Air Force, currently serving as an instructor. He also recently competed in the Warrior Games. Today the multiple medal winner speaks to students and military personnel, urging them not to give up on their dreams.

As soon as he could after Sept. 11, 2001, Joe Carroll joined the military where he served as an Army Ranger. Joe deployed to Iraq on three separate occasions where he participated in over 100 combat missions. After Joe returned home to Cincinnati, he founded Helping Hands of Cincinnati, a nonprofit that helps families fight the financial burdens of cancer. He came up with the idea after his mother, brother and many family friends were diagnosed with the disease. HHoC helps families facing cancer meet financial obligations that insurance typically doesn't cover, including travel and living expenses, physical and psychotherapy costs, deductibles and co-insurance payments. Joe also volunteers his time with the American Cancer Society.

WWII vet Raymond Matwich peformed a critical job during the war: guarding the door of the war room in which Operation Dragoon -- the invasion of south France -- was being made. General Truscott asked him to guard the door from the inside, which allowed Ray to see all the plans laid out on the table. He said the generals must have had a lot of trust in him to let him into that room. That trust was well deserved. Ray, now 92, received five Battle Stars and was discharged as a Corporal after the war ended. The Leavittsburg, Ohio, resident was active in American Legion and is a lifetime member. He was also active in the community as a baseball coach for all ages.

Above and beyond doesn't begin to cover it. Shortly after returning from Iraq, Kevin Burciaga learned he was a perfect bone marrow match for a complete stranger.
